The db1040DVC 10" subwoofer boasts a rigid polypropylene cone and durable Santoprene™ surround built to handle big power over the long run. Polk Audio tests their subs rigorously for environmental effects caused by sun, moisture, and extreme temperature changes.

The dual 4-ohm voice coils allow you to wire your system to draw max power from your mono amp or to safely hook up multiple subs. Match a db sub to a suitable enclosure, and enjoy impressive low-frequency performance rarely found in this price range.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 400 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Features

Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils
that offer flexibility in wiring. When the voice coils are wired in parallel
with each other, the woofer presents a 2-ohm mono load. When the voice coils are
wired in series with each other, the woofer presents an 8-ohm mono load. In
addition, each coil may be connected to a different amplifier channel and each
channel will see a 4-ohm load.

Polypropylene Cone: The cone is made with polypropylene, which
provides durability while being lightweight and rigid. The cone is supported by
a vented cone/coil coupler, which stiffens the cone for greater mechanical
stability and lower distortion.

Santoprene
Surround: The Santoprene surround is resistant to extremes in temperature,
humidity, and exposure to sunlight for excellent long term reliability.

Triple-vented Kapton Voice Coil
Former: Triple venting of the 4-layer Kapton Voice Coil Former, Cone/Coil
Coupler and Pole Piece contribute to the high power handling and reliability of
the db Series subs.

Break-In Period: Polk db subwoofers will achieve even greater
performance once they are thoroughly broken-in. To break in a new db Sub, play
music through it for 20 to 30 hours at moderate levels.

Enclosure Compatibility

Recommended Sealed Box Volume: Polk recommends mounting this
woofer in a sealed enclosure made out of 3/4" MDF with an internal volume of
0.66 cu/ft.

Recommended Ported Box Volume: Polk recommends a ported
enclosure made out of 3/4" MDF with an internal volume of 1.25 cu/ft using a
4" diameter x 12" long port.

Recommended Bandpass Box Volume: Polk recommends a bandpass
enclosure made of 3/4" MDF with a total internal volume of 1.65 cu/ft. The bandpass box
should have a 0.80 cu/ft sealed rear chamber and a 0.85 cu/ft ported front
chamber with 4" diameter x 9" long port.

very good bass!

Very easy to install, looks good, and hits very well and price for it is definitely a go! Installed it in my 04 Dodge Neon and I have the tube people ask if I have two 10s or a 12 incumple sub and they find out its a 10 they get amazed. I'd get another one or convince customers to get one.

Pros:great bass quality, looks awesome, easy installation, and very good for price.

Great sound for a great price

This sub is being driven by a Sound Ordnance M-1350 amp in my '98 Corvette. I mounted in a sealed stealth sub box that's .81 cubic feet installed in the center compartment under my trunk. I wired the two voice coils in parallel to yield a 2 ohm impedance. This sub sounds great! Excellent price by Crutchfield too. It's not really broken in yet (the manual says 30 hours of play time to break in), but I'm still in love with it. Buddy in customer service recommended it and I'm sure glad he did.

Pros:Sharp bass hits, good sound, really sharp looking appearance, very easy to install. I'd buy another one in a heartbeat!

Cons:Use caution when mounting the sub in your box. It comes with Allen type lag screws. Be sure they're going in straight or the head can deform the cut out in the mounting ring.

Awesome subs

I just bought 4 these polks to throw in my truck because I was lookin for some good bass and a couple people recommend these to me, and man am I glad they did cause I love these things! They hit so hard especially with my amp. I have the amp turned way down cause they were shakin my truck and everyone else's car around me it was pretty great.

Pros:Hits hard
Great design
Doesn't need massive juice to work properly
Fits in a small wedge box
Easy hook up
Pretty good price
Look great

nice quality sub especially for the price

I had to replace my jl audio 10w3 dual voice coil sub in my mustang jl audio stealth box. It lasted me a good 13 years. The Polk Audio db popped right in and looks nice. Build quality seems really good. The sensitivity seems really good also and the bass in my Mustang is back! Hard to fairly compare the jl 10w3 because of its old age but this Polk sub definitely sounds great in the jl stealthbox and saved me around 2 bills. I hope it will last as long as the jl.

What a DEAL..!!! Polk Audio db's

I always was a FAN of Polk Audio, but didn't want to spend the money... So when I seen this "DEAL" I jumped on it... After listening to my setup, my friend ordered.....

Pros:The speaker is built pretty solid w/ a fat rubber surrounding ... The dust cap design is cool an stylish..

Cons:Still has old style terminal's.. They give screws, but no Allen wrench bit.. Took time to bolt them in box, but I guess less chance of a slippage to poke your Polk... Lol
*The sound makes up for it... Bass is clean & Deeeep!!

So far, so good

Only reason I gave the "value" category a 5 star is because I got this sub half price. Within the first minute of hearing this thing I smelled heating up.... made me very nervous. But maybe it was some excess glue on the rubber? I thought it was gonna blow, but it has held up for a week so far with a Rockford fosgate 500watt amp powering it. Only have the gain half way up on the amp BTW. Otherwise you will probably blow the sub. I would not spend what these guys are asking.. maybe 10 or 20 bucks less. But like I said got it half price.

Good Free Air Sub

I have a Lexus GS 430 that has a factory sub in the rear deck. The factory sub blew out and everyone told me I needed to buy a "free air" sub or it will sound terrible. The second problem I encountered is all the manufacturers stopped making free air subs. I did not want a box taking up trunk space. The adviser at Crutchfield evaluated my situation and current factory system and recommended this sub along with a Kenwood amp. He said it will not work optimally but it will sound good. He was right! The sound and base is fantastic!

polk audio db series

Written By Ryan, lexington, ky on Wednesday, February 03, 2010

very wallet friendly yet very powerful. I have one installed in my 2001 grand prix in a 1.25 cubic ft ported box facing forward of the car. Its hooked to a cheap 250w Sony Xplod amp and running at 8 ohms and this thing packs a huge punch, for a 10". and im sure it can get louder and deeper with a better amp. It adds all the low's ive been looking for without breaking the bank. im also running db series component speakers front and back, best sounding setup ive ever done.

Unfortunate

It was quite unfortunate that after taking the time to build a box, carpet the thing, then install it in my new boat that I put this sub into the box and there was something wrong with the sub. It made good clean bass, but there was a rattle in the dust cap.

I was disappointed after owning so much other Polk Audio equipment and it being completely trouble free. I will buy Polk again, but after this experience it knocks them down a couple of points in my head.

Crutchfield of course was on top of things. They took the sub back no questions asked and I am getting a replacement MTX 10". Thank you for the trouble free replacement Crutchfield!

Decent boom for the buck

These sound pretty good. Bass is a little muddy at low volumes, but that's likely a side effect produced by the enclosure. Otherwise, great response, solid performance with 500 watts dedicated to the pair.

Great Replacement Speaker

I purchased this sub to replace an old 10" Advent sub in my home theater system that blew out after 8 years of hard use. Crutchfield's detailed specs (such as the exact cutout diameter) meant that I could purchase a sub driver that would fit my enclosure without any modifications.

The sub is installed and working fantastically. Frequency response is great, and it has restored that low end punch in my movies and video games. Bass response is tight. It's installed in a ported enclosure with a volume of about 1.5 cubic feet.
